Description
Technical field:
The present invention relates to the oil sprayer that a kind of electric-controlled petrol engine fuel injection system uses, particularly be applicable to the electric-controlled gasoline ejector of common rail electric-controlling petrol engine fuel supply system.
Background technique:
Electric-controlled gasoline ejector is the vitals of modern gasoline motor, it is accurate at present to have fuel injection quantity at the petrol engine of usefulness with electric-controlled gasoline ejector, to the fast characteristics of electric excitation signal response, but these gasoline ejector processing conditions requirements are high, difficulty is big, the cost height.
Summary of the invention:
The object of the present invention is to provide a kind of product performance high conformity but lower to the processing conditions requirement, difficulty of processing is little, and the electric-controlled gasoline ejector that cost is low requires height to solve existing electric-controlled gasoline ejector to the processing conditions of part, difficulty of processing is big, the problem that cost is high.
The technological scheme that solves the problems of the technologies described above is: a kind of electric-controlled gasoline ejector, comprise: housing, spool, the metering-orifice valve seat, guide pin bushing, unshakable in one's determination, magnetic shield, electromagnetic coil, the demagnetization structure, oil inlet pipe, spring and plastic casing, it is characterized in that: the guide pin bushing that spool is housed in it is contained in an end of housing, the endoporus of spool is equipped with spring, one end of guide pin bushing order vertically is equipped with by valve seat, O RunddichtringO IV, orifice plate, the metering-orifice valve seat that protecting cover is formed, the electromagnetic coil and the iron core of band coil holder are housed successively at the other end of housing, the endoporus of an end unshakable in one's determination is equipped with hollow opening resilient key, the one end welding of this end cylindrical and oil inlet pipe forms oil inlet passage, stalk is fixedly linked by welding to the boss at middle part and the cylindrical of housing, the other end of oil inlet pipe and plastic casing and Sealing are formed the fuel inlet fitting that joins with petrol engine oil rail, coil lead is drawn and is fixed on the plastic casing through boss via hole unshakable in one's determination, magnetic shield that unmagnetized metallic material is made and guide pin bushing be in the welding that is coaxial docking of the little end of guide pin bushing diameter, and the demagnetization structure is positioned at unshakable in one's determination and spool abutting end.
Because adopt said structure, the present invention with the beneficial effect that existing electric-controlled gasoline ejector is compared is: be easy to producing stay-in-grade product in enormous quantities under the processing conditions cheaply.This is because adopted above structural type, makes that processing technology is simplified, the cooperation between the part is more convenient, mainly contain following some:
One, processing technology simplification, processing and fabricating convenience:
1, the housing of oil sprayer is made of permeability magnetic material, and housing plays the effect of magnetic conduction, is the part of magnetic circuit, cylindrical has a groove that the O RunddichtringO is installed, sealing when being used to install, the endoporus of housing is the secondary shoulder hole, adds the coaxality that is easy to guarantee the hole man-hour;
2, the endoporus of guide pin bushing is a secondary shoulder hole, the processing of endoporus can be finished by a clamping, the coaxality of secondary shoulder hole is guaranteed, valve seat and spool are installed in the guide pin bushing, its working position is only relevant with guide pin bushing, and irrelevant with nozzle holder, has reduced the fuel leakage that causes because of valve seat and housing coaxiality deviation to greatest extent, thereby reduced the requirement of housing machining accuracy, reduced processing cost;
3, middle part boss and housing vertically unshakable in one's determination is assembled together closely, and housing cylindrical and connecting part unshakable in one's determination welding are fixing;
4, spool is the part of a weak point, light weight, and spool is made of permeability magnetic material, and cylindrical is the secondary multidiameter shaft shape of arc transition, is the through hole of a secondary along valve core axis, and the little end of valve core diameter has welded a steel ball; Steel ball is used for playing when contacting with valve seat the effect of sealing, and spool plays the effect of armature and logical oil, and the spool external cylindrical surface plays the effect of guiding and is easy to processing.
Two, use a plurality of O RunddichtringOs to form flexible sealing dexterously, both guaranteed airtight quality, improved the assembly technology performance again:
Do not adopt the fit sealing of rigidity between valve seat and the guide pin bushing, but between valve seat and guide pin bushing, reserved the gap, valve seat can be placed on the seam of guide pin bushing when mounted easily, be convenient to the correcting of valve seat and spool like this, the valve seat O RunddichtringO IV that packs between valve seat and the guide pin bushing prevents fuel leakage, valve seat and orifice plate do not adopt the fit sealing of rigidity yet, the end face of valve seat has an annular groove of placing O type circle, after putting into valve seat O RunddichtringO II orifice plate and protecting cover are packed into, fixing in the end face welding of guide pin bushing and protecting cover.
Three, improve the switch on and off characteristic of solenoid valve, improved the high frequency response characteristic of oil sprayer.
The present invention welds together with the magnetic shield made from non-magnet material coaxially at the less end of guide pin bushing diameter, make by guide pin bushing and increase to the magnetic resistance the iron core, the spool that forces the magnetic line of force to be done by permeability magnetic material in being installed in guide pin bushing arrives unshakable in one's determination, formation is from iron core, shell, guide pin bushing, spool, air gap between spool and the iron core, nullification magnetic sheet make spool obtain the electromagnetic force that moves in guide pin bushing to magnetic loop unshakable in one's determination.Simultaneously, on the end face adjacent unshakable in one's determination, apply or be welded with the unmagnetized material with spool, nullification magnetic sheet is a shallow disc shape, also can be flat, because the existence of the unmagnetized material of nullification magnetic sheet or coating, when electric excitation signal stops, having reduced the adverse effect of permeability magnetic material coercivity, improved the high frequency response characteristic of oil sprayer the spool seating velocity.
Below, the technical characteristics to the present invention's electric-controlled gasoline ejector is further described in conjunction with the accompanying drawings and embodiments.
